1. A sex identification method for Chinese mitten crab Eriocheir sinensis, wherein the sex identification method is achieved by identifying a specific DNA sequence which is shown in SEQ ID No: 1; the sex identification method comprises following steps:
S1, extracting genomic DNA of Chinese mitten crab Eriocheir sinensis;
S2, PCR amplification using the genomic DNA as template; an upstream primer for PCR amplification is as shown in SEQ ID No: 2 and a downstream primer is as shown in SEQ ID No: 3;
S3, examining amplified products by agarose electrophoresis, and those with specific amplified bands are females, otherwise they are males.
